Description

Technical Field

[0001] This invention belongs to the field of cigarette technology, and in particular relates to a cigarette with a watermelon-like filter and a watermelon flavor. Background Technology

[0002] As consumer demands continue to evolve and upgrade, cigarette filters are also constantly developing, reflected in innovations in materials, structure, and flavor. For example, to enrich the sensory experience of cigarettes, a specific aroma is loaded inside the filter, providing smokers with an additional sensory experience beyond the traditional tobacco flavor, such as natural or synthetic aromas like vanilla or mint. However, currently, there is a lack of cigarettes that offer both a sensory experience of a particular flavor and a visual experience corresponding to that flavor.

[0003] Therefore, developing a filter segment structure and appearance design that is compatible with a specific flavor of cigarette, so that consumers can not only smell the flavor but also see its color immediately when smoking that flavored cigarette, is an urgent problem to be solved in the current cigarette technology field. Summary of the Invention

[0004] In view of this, the present invention provides a cigarette with a watermelon-like filter and a watermelon flavor, in order to at least partially solve the above-mentioned technical problems. The technical solution provided by the present invention is as follows.

[0005] As one aspect of the present invention, a cigarette with a watermelon-like filter tip and a watermelon flavor is provided, comprising: a tobacco segment, a cooling and retaining segment, a filter rod segment with a watermelon-like structure connected in sequence, and a tipping paper wrapping the cooling and retaining segment, the filter rod segment, and part of the tobacco segment, wherein the cooling and retaining segment, the filter rod segment, and the tipping paper are assembled into a filter tip segment; wherein the filter rod segment includes an inner core with a watermelon pulp-like structure and an outer shell with a watermelon rind appearance, the inner core having multiple orderly distributed through holes, the opening end of the through holes having a teardrop-shaped structure that is narrow at one end and wide at the other end, and the color of the opening end is contrasted with the color of the surrounding inner core to create the color of watermelon seeds; wherein the filter tip segment is flavored with watermelon flavoring.

[0006] In the technical solution of this invention, a tipping paper is used to connect the cooling section, the filter rod section, and part of the tobacco section to form a complete cigarette structure, preventing the filter section from separating from the tobacco section during smoking and ensuring the stability of the cigarette shape. The filter section of this invention consists of a cooling section, a filter rod section with a watermelon-like structure, and tipping paper. The filter rod section is designed with an inner core with a watermelon flesh-like structure and an outer shell with a watermelon rind appearance. Multiple through holes are opened in the inner core. The shape and color of watermelon seeds are constructed through the structure of the opening end of the through holes and the color contrast between the opening end of the through holes and the surrounding inner core. Watermelon flavoring is added to the filter section, allowing consumers to achieve a dual visual and sensory experience of watermelon during smoking. Attached Figure Description

[0016] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the invention for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0017] In implementing this invention, it was discovered that current methods enrich the sensory experience of cigarette smoking by adding natural or compound flavorings to the filter segment, or by designing the structure and appearance of the filter segment to enhance the visual experience. However, currently available filter segments with special structures often only offer a unique visual experience, lacking a sensory experience of taste; or cigarettes with a certain sensory flavor do not offer a unique visual sensory experience. Therefore, developing a structural and aesthetic design for a filter segment that works in conjunction with a specific flavor of cigarette, allowing consumers to not only smell the flavor but also see its color when smoking that flavored cigarette, is a problem that urgently needs to be solved in the field of cigarette technology.

[0018] In response, this invention provides a watermelon-flavored cigarette filter with a watermelon structure and appearance. When consumers smoke the watermelon-flavored cigarette, they can see the watermelon-like appearance and structure at the first moment, while also enjoying the watermelon taste, enhancing the dual experience of visual and gustatory senses and improving the consumer experience.

[0019] Specifically, the cigarette with a watermelon-like filter tip and watermelon flavor provided by the present invention includes: a tobacco segment, a cooling and retaining segment, a filter rod segment with a watermelon-like structure connected in sequence, and a tipping paper wrapping the cooling and retaining segment, the filter rod segment, and part of the tobacco segment, wherein the cooling and retaining segment, the filter rod segment, and the tipping paper are assembled into a filter tip segment; wherein the filter rod segment includes an inner core with a watermelon pulp-like structure and an outer shell with a watermelon rind appearance, wherein the inner core has multiple orderly distributed through holes, and the opening end of the through holes has a teardrop-shaped structure that is narrow at one end and wide at the other end, and the color of watermelon seeds is constructed by the color contrast between the opening end and the surrounding inner core; wherein watermelon flavoring is added to the filter tip segment.

[0020] In embodiments of the present invention, a tipping paper is used to connect the cooling section, the filter rod section, and part of the tobacco section to form a complete cigarette structure. The presence of the tipping paper prevents the cooling section, the filter rod section, and the tobacco section from separating during smoking, ensuring the stability of the cigarette's shape; it also serves aesthetic purposes, brand identification, heat insulation, and anti-scalding functions. The filter section of the present invention includes a cooling section, a filter rod section, and tipping paper wrapping the cooling section and the filter rod section. One end of the cooling section is connected to the tobacco section, and the other end is connected to the filter rod section. The presence of the cooling section can both trap harmful components such as tar in the smoke and reduce the temperature of the cigarette. The present invention designs the filter rod section with an inner core having a watermelon pulp-like structure (such as a cartoon watermelon structure) and an outer shell having a watermelon rind appearance. Multiple through holes are opened in the inner core, and the opening end of the through holes is designed as a teardrop shape, narrow at one end and wide at the other end. The color contrast between the open section and the surrounding inner core simulates the shape of watermelon seeds. In addition to satisfying the visual experience of watermelon, the presence of through holes can also reduce the resistance during suction, thereby trapping harmful substances and lowering the temperature. At the same time, it can also provide a visual experience of watermelon. Combined with the addition of watermelon-flavored flavoring to the filter section, it can achieve a dual sensory experience of watermelon, both visually and in terms of taste.

[0021] According to an embodiment of the present invention, the tobacco segment includes various tobacco leaves and additives (such as humectants, combustion aids, preservatives, etc.).

[0022] According to an embodiment of the present invention, the interception and cooling section is a cellulose acetate tow section, wherein the cellulose acetate tow section includes cellulose acetate tow, and the cigarette of the present invention is a conventional cigarette. In the cigarette, the cellulose acetate tow section is the core component of the filter section. Utilizing its high specific surface area and the microporous channels formed between the fibers, when smoke or aerosol passes through the cellulose acetate tow section, it can intercept some harmful substances in the smoke or aerosol through physical adsorption and interception. By controlling the filling density of the cellulose acetate tow, the draw resistance and filtration effect can be balanced. When smoke or aerosol passes through the cellulose acetate tow, it comes into contact with the fiber surface, and some heat is absorbed by the cellulose acetate tow, which can play a certain role in cooling and avoid the problem of burning the mouth. The cellulose acetate tow also has a certain degree of elasticity and strength, which can play a certain supporting role and prevent it from collapsing due to external pressure during the draw, ensuring the smooth passage of smoke or aerosol.

[0023] According to embodiments of the present invention, the cooling section can also be a hollow section. As the name suggests, a hollow section refers to a partially hollow area within the cigarette. In this case, the cigarette of the present invention is a heated cigarette, also known as a heated non-combustible cigarette. During inhalation, the smoke or aerosol exchanges heat with the outside air within the hollow section, achieving cooling and preventing discomfort caused by excessively high temperatures entering the mouth. The presence of the hollow section also reduces the resistance of the smoke or aerosol, ensuring smooth inhalation. The stiffness of the hollow section also ensures smooth flow of smoke or aerosol. The hollow section of the present invention can be composed of cellulose acetate bundles, i.e., hollow cellulose acetate bundles, which have high hardness and stiffness.

[0024] This invention replaces some of the cellulose acetate tow segments or hollow segments in traditional cigarettes with a watermelon filter rod featuring a cartoon watermelon structure. Used in conjunction with a watermelon-flavored filter tip, it allows consumers to immediately perceive the watermelon (cartoon watermelon structure) characteristics, enhancing their experience of the watermelon flavor. Furthermore, the cellulose acetate tow segments or hollow segments can be flexibly switched as needed to prepare different types of cigarettes.

[0025] According to an embodiment of the present invention, the cellulose acetate tow segment also includes a fragrance thread located at the center of the cellulose acetate tow segment, which can release fragrance during use, blend with the fragrance of the tobacco itself, and enhance the aroma, thereby improving the consumer's experience.

[0026] According to embodiments of the present invention, the watermelon-flavored flavoring can be added to at least one of the hollow section, the cellulose acetate tow, the filter rod section, and the flavoring thread. The methods for adding the flavoring include impregnation, coating, spraying, etc., which will not be described in detail here. For example, the watermelon-flavored flavoring can be added to the inner wall of the hollow section and / or the filter rod section; it can also be added to the entire hollow section, i.e., to the hollow cellulose acetate tow.

[0027] According to embodiments of the present invention, the thickness of the outer shell accounts for 6%-30% of the diameter of the filter rod segment. For example, it can be 6%, 10%, 12%, 15%, 18%, 20%, 25%, 30%, etc., or any value within this range, which is not limited in detail here. The present invention limits the ratio of the thickness of the outer shell (i.e., watermelon rind) to the diameter of the filter rod segment to 6%-30%, ensuring that the filter rod with the cartoon watermelon structure has a beautiful and harmonious appearance.

[0028] According to an embodiment of the present invention, in the open end structure of the through hole of the present invention, the narrow end faces the center of the inner core. The through holes can be distributed in a circumferential array, or a single through hole can be provided at the center of the inner core. The number of through holes in the inner core can be 4-20, or can be flexibly set according to requirements; the circumference of the through hole is 1.8-10mm, and the total area of ​​all through holes is 5-60% of the total area of ​​the end face of the filter rod segment.

[0029] According to an embodiment of the present invention, the filter rod segment is made of two layers of materials of different colors. The inner core is the same as or similar in color to the watermelon flesh, and the outer shell is the same as or similar in color to the watermelon rind. This can be understood as follows: in the filter rod segment with a cartoon watermelon structure, the inner core is composed of a red material with the same or similar color to the watermelon flesh, and the outer shell is composed of a green material with the same or similar color to the watermelon rind. One or more through holes are formed in the inner core (i.e., the watermelon flesh). The opening end of the through hole has a teardrop-shaped structure that is narrow at one end and wide at the other. The outer shell (i.e., the watermelon rind) is composed of alternating vertical stripes of dark green and light green. The thickness of the watermelon rind (i.e., the outer shell) is as defined above. Because the inner core with the cartoon watermelon flesh structure is a darker red or pink, the opening end of the through hole contrasts with the color of the surrounding inner core, thus creating a darker or blacker color on the end face of the filter rod segment, resulting in a black visual effect similar to watermelon seeds at the through holes; or a light-colored visual effect at certain angles, analogous to seedless watermelons. Thus, the entire filter tip section now features the colors and shapes of watermelon rind, watermelon flesh with a cartoonish structure, and watermelon seeds, providing consumers with a visual sensory experience.

[0030] According to an embodiment of the present invention, when the filter rod segment includes an inner core material, a layer of molded paper is wrapped around the outer surface of the inner core as an outer shell, or a tipping paper is used as an outer shell. It can be understood that the filter rod segment with a cartoon watermelon structure consists of an inner core made of a red material that is the same or similar in color to the watermelon flesh, and an outer shell made of molded paper or tipping paper wrapped around the outer surface of the inner core; wherein, the inner core (i.e., the watermelon flesh) has one or more through holes, the opening end of which has a teardrop-shaped structure that is narrow at one end and wide at the other; the color of the molded paper or tipping paper is a green material that is the same or similar in color to the watermelon rind, and it can also be composed of alternating dark green and light green vertical stripes to form the watermelon rind, the thickness of which is as defined above. Furthermore, the inner core of the cartoon watermelon can be a darker red or pink, creating a contrast between the opening of the through hole and the surrounding inner core color. This makes the end face of the filter section appear darker or blacker, creating a black visual effect similar to watermelon seeds at the through hole. Alternatively, it can have a lighter visual effect at certain angles, similar to seedless watermelons. The entire end face of the filter section can simultaneously have the color and shape of watermelon rind, cartoon-structured watermelon flesh, and watermelon seeds, providing consumers with a visual experience.

[0031] According to embodiments of the present invention, the filter rod segment is composed of at least one of solid silica gel, polypropylene, polylactic acid, colored cellulose acetate tow, and forming paper. This can be understood as the filter rod segment having a solid silica gel core and a silica gel sleeve as the outer shell, differing only in color. Alternatively, the core may be red cellulose acetate tow, and the outer shell may be green cellulose acetate tow wrapped around the outer surface of the core. Alternatively, the core may be solid silica gel, and the outer shell may be forming paper; or the core may be solid silica gel, and the outer shell may be splicing paper.

[0032] According to embodiments of the present invention, depending on the materials of the inner core and outer shell in the filter rod segment, the filter rod segment can be formed in one step, or formed by molding the inner core and outer shell in stages and then assembled. For example, when both the inner core and outer shell are made of silicone, they can be prepared by one-step molding; or, the inner core and outer shell can be prepared separately according to dimensions, and then assembled. Alternatively, when the inner core is made of cellulose acetate tow and the outer shell is made of molded paper, they can be formed in stages and then assembled.

[0033] According to an embodiment of the present invention, the total length of the filter tip section is 10-30 mm, the length of the filter rod section is 4-26 mm, and the remainder is a trapping and cooling section. By controlling the length of the filter rod section, partial replacement of the trapping and cooling section can be achieved, balancing cost and visual experience.

[0034] According to embodiments of the present invention, the cigarettes of the present invention can be coarse or fine cigarettes, and filter sections can be flexibly assembled as needed.

[0035] The cigarettes of the present invention will be described in detail below with reference to specific embodiments.

Figure 2 This is a schematic diagram of the cigarette structure in Embodiment 1 of the present invention, in which the cooling section is composed of cellulose acetate tow. Figure 3 This is a schematic diagram of the end face of the filter rod segment in Embodiment 1 of the present invention. Figure 4A This is a physical image of the cigarette with a watermelon-like filter and watermelon flavor, as shown in Embodiment 1 of the present invention. Figure 4B This is a photograph of the end face of a cigarette with a watermelon-like filter and watermelon flavor, as shown in Embodiment 1 of the present invention.

[0038] like Figures 1-3As shown, the cigarette with a watermelon-like filter and watermelon flavor includes a tobacco segment 2, a cooling and retaining section 11, a filter rod segment 10 with a watermelon-like structure, and a tipping paper 3 that wraps the cooling and retaining section 11, the filter rod segment 10, and part of the tobacco segment 2, connected in sequence. The cooling and retaining section 11, the filter rod segment 10, and the tipping paper 3 are assembled to form the filter segment 1. The cooling and retaining section 11 is a cellulose acetate tow segment, and a fragrance thread 12 is provided at the center of the cellulose acetate tow segment. The cellulose acetate tow segment is composed of cellulose acetate tows 13, and watermelon flavoring is added to the cellulose acetate tows 13, the filter rod segment 10, or the fragrance thread 12. The filter rod segment 10 includes an inner core 102 with a watermelon flesh-like structure and an outer shell 101 with a watermelon rind appearance. That is, the inner core 102 has the structure and appearance of a cartoon watermelon flesh (i.e., the watermelon flesh is red and has the texture of watermelon flesh), and the outer shell 101 is composed of alternating dark green and light green vertical stripes. The inner core 102 and the outer shell 101 are made of silicone material of different colors. The entire watermelon filter rod is molded into a single structure. Then, tipping paper is wrapped around the outer surface of the cooling section, the filter rod section, and part of the tobacco section. The thickness of the outer shell 101 (i.e., the watermelon rind) accounts for 6%-30% of the diameter of the entire filter rod section 10. The inner core 102 has multiple through holes 103. The through holes 103 include a through hole located at the center of the inner core 102, and 4-20 axially distributed through holes arranged in an array around the central through hole 103. The opening end of the through hole 103 has a teardrop-shaped structure that is narrow at one end and wide at the other end. In the axially distributed through holes, the narrow end of the opening faces the center of the inner core 102, which helps to increase the number of through holes in the entire watermelon filter rod while also being aesthetically pleasing. The color of watermelon seeds is created by contrasting the color of the open end of the through hole with the color of the surrounding inner core 102. The through hole 103, which has the shape of a watermelon seed, has a circumference of 2.8 mm, and the total area of ​​all through holes is 27% of the total area of ​​the end face of the filter rod segment.

[0039] Example 2

[0040] Example 2 has the same characteristics as in Example 1. Figures 1-3 The same structure, the difference lies in the way the inner core 102 and the outer shell 101 are formed in the filter rod section 10.

[0041] Specifically, the cigarette with a watermelon-like filter and watermelon flavor includes a tobacco segment 2, a cooling and retaining section 11, a filter rod segment 10 with a watermelon-like structure, and a tipping paper 3 that wraps the cooling and retaining section 11, the filter rod segment 10, and part of the tobacco segment 2, connected in sequence. The cooling and retaining section 11, the filter rod segment 10, and the tipping paper 3 that wraps the cooling and retaining section 11 and the filter rod segment 10 are assembled to form the filter segment 1. The cooling and retaining section 11 is a cellulose acetate tow segment, and a flavoring thread 12 is provided at the center of the cellulose acetate tow segment. The cellulose acetate tow segment is composed of cellulose acetate tows 13, and watermelon-flavored flavoring is added to the cellulose acetate tows 13 or the flavoring thread 12. The filter rod segment 10 includes an inner core 102 with a watermelon flesh-like structure and an outer shell 101 with a watermelon rind appearance. Specifically, the inner core 102 has the structure and appearance of a cartoon watermelon flesh (i.e., the watermelon flesh is red and has watermelon flesh texture), and the outer shell 101 consists of alternating dark green and light green vertical stripes. The inner core 102 and outer shell 101 are made of silicone materials of different colors. A green silicone sleeve is wrapped around the outer surface of the red silicone inner core 102 (resembling watermelon flesh) to form the outer shell 101, thus creating the filter rod segment with a cartoon watermelon structure and appearance. Tipping paper is wrapped around the outer surfaces of the cooling section, the filter rod segment, and part of the tobacco segment. The thickness of the outer shell 101 (i.e., the watermelon rind) accounts for 6%-30% of the total diameter of the filter rod segment 10. The inner core 102 has multiple through holes 103, including a central through hole and 4-20 axially distributed through holes arranged in an array around the central through hole 103. The opening of each through hole 103 has a teardrop shape, narrow at one end and wide at the other. In the axially distributed through holes, the narrower opening faces the center of the inner core 102, which helps increase the number of through holes in the entire watermelon filter rod while also enhancing its aesthetic appeal. The color of watermelon seeds is created by contrasting the color of the through hole openings with the surrounding inner core 102. The through holes 103 with a watermelon seed shape have a circumference of 1.8-10 mm, and the total area of ​​all through holes is 5-60% of the total area of ​​the filter rod end face.

[0042] Example 3

[0043] Example 3 has the same characteristics as in Example 1. Figures 1-3 The same structure, the difference is that the outer shell 101 in the filter rod section 10 is made of molded paper.

[0044] Specifically, the cigarette with a watermelon-like filter and watermelon flavor includes a tobacco segment 2, a cooling and retaining section 11, a filter rod segment 10 with a watermelon-like structure, and a tipping paper 3 that wraps the cooling and retaining section 11, the filter rod segment 10, and part of the tobacco segment 2, connected in sequence. The cooling and retaining section 11, the filter rod segment 10, and the tipping paper 3 that wraps the cooling and retaining section 11 and the filter rod segment 10 are assembled to form the filter segment 1. The cooling and retaining section 11 is a cellulose acetate tow segment, and a flavoring thread 12 is provided at the center of the cellulose acetate tow segment. The cellulose acetate tow segment is composed of cellulose acetate tows 13, and watermelon-flavored flavoring is added to the cellulose acetate tows 13 or the flavoring thread 12. The filter rod segment 10 includes an inner core 102 with a watermelon flesh-like structure and an outer shell 101 with a watermelon rind appearance. Specifically, the inner core 102 has the structure and appearance of a cartoon watermelon flesh (i.e., the watermelon flesh is red and has the texture of watermelon flesh), and the outer shell 101 consists of alternating dark green and light green vertical stripes. The inner core 102 is made of red silicone, resembling watermelon flesh, and the outer shell 101 is a molding paper of a certain thickness. The outer surface of this molding paper has alternating dark green and light green vertical stripes. By wrapping the molding paper around the outer surface of the inner core 102, a filter rod segment with a cartoon watermelon structure and appearance is assembled. Tipping paper is then wrapped around the outer surfaces of the cooling section, the filter rod segment, and part of the tobacco segment. The thickness of the molding paper (outer shell, i.e., the watermelon rind) accounts for 6%-30% of the total diameter of the filter rod segment 10. The inner core 102 has multiple through holes 103, including a central through hole and 4-20 axially distributed through holes alternating around the central through hole 103. The opening of each through hole 103 has a teardrop shape, narrow at one end and wide at the other. In the axially distributed through holes, the narrower opening faces the center of the inner core 102, which increases the number of through holes in the entire watermelon filter rod while also enhancing its aesthetic appeal. The color of watermelon seeds is created by contrasting the opening of the through holes with the surrounding color of the inner core 102. The through holes 103 with a watermelon seed shape have a circumference of 1.8-10 mm, and the total area of ​​all through holes is 5-60% of the total area of ​​the filter rod end face.

[0045] Example 4

[0046] Example 4 has the same characteristics as in Example 1. Figures 1-3 The same structure, the difference is that the outer shell of the filter rod section 10 is a splicing paper 3.

[0047] Specifically, the cigarette with a watermelon-like filter and watermelon flavor includes a tobacco segment 2, a cooling and retaining section 11, a filter rod segment 10 with a watermelon-like structure, and a tipping paper 3 that wraps the cooling and retaining section 11, the filter rod segment 10, and part of the tobacco segment 2, connected in sequence. The cooling and retaining section 11, the filter rod segment 10, and the tipping paper 3 that wraps the cooling and retaining section 11 and the filter rod segment 10 are assembled to form the filter segment 1. The cooling and retaining section 11 is a cellulose acetate tow segment, and a flavoring thread 12 is provided at the center of the cellulose acetate tow segment. The cellulose acetate tow segment is composed of cellulose acetate tows 13, and watermelon-flavored flavoring is added to the cellulose acetate tows 13 or the flavoring thread 12. The filter rod segment 10 includes an inner core 102 with a watermelon flesh-like structure and an outer shell 101 with a watermelon rind appearance. Specifically, the inner core 102 has the structure and appearance of a cartoon watermelon flesh (i.e., the watermelon flesh is red and has the texture of watermelon flesh), and the outer shell 101 consists of alternating dark green and light green vertical stripes. The inner core 102 is made of red silicone, resembling watermelon flesh. The attaching paper 3 serves as the outer shell 101 of the filter rod segment 10. The outer surface of the attaching paper 3 is composed of alternating light green and dark green vertical stripes. By wrapping the attaching paper 3 around the outer surface of the inner core 102, a filter rod segment with a cartoon watermelon structure and appearance is assembled. The thickness of the attaching paper (outer shell, i.e., watermelon rind) accounts for 6%-30% of the total diameter of the filter rod segment 10. The inner core 102 has multiple through holes 103, including a central through hole and 4-20 axially distributed through holes alternating around the central through hole 103. The opening of each through hole 103 has a teardrop shape, narrow at one end and wide at the other. In the axially distributed through holes, the narrower opening faces the center of the inner core 102, which increases the number of through holes in the entire watermelon filter rod while also enhancing its aesthetic appeal. The color of watermelon seeds is created by contrasting the opening of the through holes with the surrounding color of the inner core 102. The through holes 103 with a watermelon seed shape have a circumference of 1.8-10 mm, and the total area of ​​all through holes is 5-60% of the total area of ​​the filter rod end face.

[0048] Example 5

[0049] Example 5 has the same characteristics as in Example 1. Figures 1-3 The same structure, the difference is that the inner core 102 and the outer shell 103 in the filter rod section 10 are made of two different colored cellulose acetate bundles.

[0050] Specifically, the cigarette with a watermelon-like filter and watermelon flavor includes a tobacco segment 2, a cooling and retaining section 11, a filter rod segment 10 with a watermelon-like structure, and a tipping paper 3 that wraps the cooling and retaining section 11, the filter rod segment 10, and part of the tobacco segment 2, connected in sequence. The cooling and retaining section 11, the filter rod segment 10, and the tipping paper 3 that wraps the cooling and retaining section 11 and the filter rod segment 10 are assembled to form the filter segment 1. The cooling and retaining section 11 is a cellulose acetate tow segment, and a flavoring thread 12 is provided at the center of the cellulose acetate tow segment. The cellulose acetate tow segment is composed of cellulose acetate tows 13, and watermelon-flavored flavoring is added to the cellulose acetate tows 13 or the flavoring thread 12. The filter rod segment 10 includes an inner core 102 with a watermelon flesh-like structure and an outer shell 101 with a watermelon rind appearance. Specifically, the inner core 102 has the structure and appearance of a cartoon watermelon flesh (i.e., the watermelon flesh is red and has watermelon flesh texture), and the outer shell 101 consists of alternating dark green and light green vertical stripes. The inner core 102 is composed of red acetate cellulose filaments resembling watermelon flesh, and the outer shell 101 is composed of alternating dark green and light green acetate cellulose filaments. The filter rod segment with a cartoon watermelon structure and appearance is assembled by wrapping the outer shell 101 around the outer surface of the inner core 102 and then wrapping it with forming paper. Subsequently, tipping paper is wrapped around the outer surfaces of the cooling section, the filter rod segment, and part of the tobacco segment. The thickness of the outer shell 101 (i.e., the watermelon rind) accounts for 6%-30% of the total diameter of the filter rod segment 10. The inner core 102 has multiple through holes 103, including a central through hole and 4-20 axially distributed through holes alternating around the central through hole 103. The opening of each through hole 103 has a teardrop shape, narrow at one end and wide at the other. In the axially distributed through holes, the narrower opening faces the center of the inner core 102, which increases the number of through holes in the entire watermelon filter rod while also enhancing its aesthetic appeal. The color of watermelon seeds is created by contrasting the opening of the through holes with the surrounding color of the inner core 102. The through holes 103 with a watermelon seed shape have a circumference of 1.8-10 mm, and the total area of ​​all through holes is 5-60% of the total area of ​​the filter rod end face.

[0051] Example 6

[0052] Figure 5 This is a schematic diagram of a heated cigarette structure in Embodiment 6 of the present invention, in which the cooling section is a hollow section.

[0053] like Figure 5 As shown, the difference between Example 6 and Example 5 is that the cooling section 11 is a hollow section 14, and the cigarette of the present invention is a heated cigarette.

[0054] Specifically, the cigarette with a watermelon-like filter and watermelon flavor includes a tobacco segment 2, a cooling and retaining section 11, a filter rod segment 10 with a watermelon-like structure, and a tipping paper 3 that wraps the cooling and retaining section 11, the filter rod segment 10, and part of the tobacco segment 2, connected in sequence. The cooling and retaining section 11, the filter rod segment 10, and the tipping paper 3 that wraps the cooling and retaining section 11 and the filter rod segment 10 are assembled to form the filter segment 1. The cooling and retaining section 11 is a hollow segment 14, and the inner walls of the hollow segment 14 and the filter rod segment 10 are coated with watermelon-flavored flavoring. The filter rod segment 10 includes an inner core 102 with a watermelon flesh-like structure and an outer shell 101 with a watermelon rind appearance. That is, the inner core 102 has the structure and appearance of a cartoon watermelon flesh (i.e., the watermelon flesh is red and has the texture of watermelon flesh), and the outer shell 101 is composed of alternating dark green and light green vertical stripes. The inner core 102 is made of red watermelon flesh-colored cellulose acetate bundles, while the outer shell 101 is made of alternating dark green and light green cellulose acetate bundles. The filter rod segment with a cartoon watermelon structure and appearance is assembled by wrapping the outer shell 101 around the outer surface of the inner core 102 and then wrapping it with forming paper. Tipping paper is then wrapped around the surfaces of the cooling section, the filter rod segment, and part of the tobacco segment. The thickness of the outer shell 101 (i.e., the watermelon rind) accounts for 6%-30% of the total diameter of the filter rod segment 10. The inner core 102 has multiple through holes 103, including a central through hole and 4-20 axially distributed through holes alternating around this central through hole 103. The opening of each through hole 103 has a teardrop shape, narrow at one end and wide at the other. In the axially distributed through holes, the narrower opening faces the center of the inner core 102, which increases the number of through holes in the entire watermelon filter rod while also enhancing its aesthetic appeal. The color of watermelon seeds is created by contrasting the color of the open end of the through hole with the color of the surrounding inner core 102. The through hole 103, which has the shape of watermelon seeds, has a circumference of 1.8-10mm, and the total area of ​​all through holes is 5-60% of the total area of ​​the end face of the filter rod segment.

[0055] Example 7

[0056] Example 7 has the following characteristics: Figure 5 The structure shown differs from that of Example 6 in that it does not contain molding paper.

[0057] Specifically, the cigarette with a watermelon-like filter and watermelon flavor includes a tobacco segment 2, a cooling and retaining section 11, a filter rod segment 10 with a watermelon-like structure, and a tipping paper 3 that wraps the cooling and retaining section 11, the filter rod segment 10, and part of the tobacco segment 2, connected in sequence. The cooling and retaining section 11, the filter rod segment 10, and the tipping paper 3 that wraps the cooling and retaining section 11 and the filter rod segment 10 are assembled to form the filter segment 1. Specifically, the cooling and retaining section 11 is a hollow segment 14, and the inner wall of the hollow segment 14 is coated with watermelon-flavored flavoring. The filter rod segment 10 includes an inner core 102 with a watermelon flesh-like structure and an outer shell 101 with a watermelon rind appearance. That is, the inner core 102 has the structure and appearance of a cartoon watermelon flesh (i.e., the watermelon flesh is red and has the texture of watermelon flesh), and the outer shell 101 is composed of alternating dark green and light green vertical stripes. The inner core 102 is composed of red watermelon flesh-colored cellulose acetate bundles, while the outer shell 101 is composed of alternating dark green and light green cellulose acetate bundles. By wrapping the outer shell 101 around the outer surface of the inner core 102, a filter rod segment with a cartoon watermelon structure and appearance is assembled. Then, tipping paper is wrapped around the surfaces of the cooling section, the filter rod segment, and part of the tobacco segment to form the filter tip segment. The thickness of the outer shell 101 (i.e., the watermelon rind) accounts for 6%-30% of the total diameter of the filter rod segment 10. The inner core 102 has multiple through holes 103, including a central through hole and 4-20 axially distributed through holes alternating around this central through hole 103. The opening end of each through hole 103 has a teardrop shape, narrow at one end and wide at the other. In the axially distributed through holes, the narrower end faces the center of the inner core 102, which helps increase the number of through holes in the entire watermelon filter rod while also enhancing its aesthetic appeal. The color of watermelon seeds is created by contrasting the color of the open end of the through hole with the color of the surrounding inner core 102. The through hole 103, which has the shape of watermelon seeds, has a circumference of 1.8-10mm, and the total area of ​​all through holes is 5-60% of the total area of ​​the end face of the filter rod segment.
